RAFT Polymerization of Styrene Using Dithioester with Anthracene Z Group as Chain Transfer Agent

Abstract

A novel dithioester, bearing anthracene as Z group, benzyl anthracene-10-carbodithioate (BAC) was successfully synthesized and used as the RAFT agent for the RAFT polymerizations of styrene (St). The results indicated that the polymerization presented the characteristics of "living"/controlled radical polymerization.

2‐oxo‐tetrahydrofuran‐3‐yl 9H‐carbazole‐9‐carbodithioate mediated reversible addition‐fragmentation chain transfer (RAFT) polymerization

“…7,8 However, to our best knowledge, there are few reports about the synthesis of end-labeled polymer via reversible addition-fragmentation chain transfer (RAFT) polymerization. Actually, according to the RAFT mechanism (Scheme 1), Z and R groups of RAFT agents will be capped at the ends of the polymer.…”
